IMPROVEMENT IN SCRAPERS.

Specification forming part of Letters Patent No. 121,576, dated December5, 1871.

To all whom it may concern:

Be it known that I, GEORGE W. BAYLY, of Stuyvesant, in the county ofColumbia and State of New York, have invented a new and usefulImprovement in Grading-Scraper and Road- Uleaner; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to make and use thesame, reference being had to the accompanying drawing forming part ofthis specification.

Figure l is a top view of my improved scraper. Fig. 2 is a detailsectional View of the same taken through the line a' a', Fig. 1. Fig. 3is a detail view of the knife or shear.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved grading scraperfor grading roads, lawns, 85o., which shall be simple in construction,effective in operation, and convenient in use, and which may readily beadjusted for use for cleaning grass, Sac., from private roads; and itconsists in the construction and combination of various parts of themachine, as hereinafter more fully described.

A is a thick heavy plank set edg'ewise, and to the lower part of theforward side of which is attached the scraper-plate B, which shouldproject below the lower vpart of the plank A. rIo the middle of theforward side of the plank A is attached the tongue C in such a way thatit may have a free lateral but no vertical movement. To the forward sideof the plank A, near its ends, are rigidly attached the ends of a curvedbar, D, which passes through a keeper, E, attached to the under side ofthe tongue C. The curved bar D has several holes formed through it toreceive the pin F, which passes down through the tongue C, through oneof the holes in the curved bar D, and through the keeper E, so as tohold the scraper A B and tongue C rigidly in place when adjusted at anydesired angle with each other. This construction enables the scraper tobe readily adjusted at right angles with the tongue for filling uphollows in the ground or roadway being graded, or at any desiredinclination with said tongue for moving the dirt laterally for iillingthe wagon-ruts in or rounding up the center of the roadway. rIo thecenter of the rear side of the' plank A is attached an eyebolt or plate,G, into the eye of which is hooked the hook H attached to the center ofthe U- shaped bar I, the arms of which pass through holes in the axle J,and have several holes formed in them to receive the pins or bolts K bywhich they are seciued to said axle. This construction allows the axle Jto be adjusted closer to or further from the scraper A B, according tothe inclination at which said scraper may be adjusted, the object beingto have the axle J as near as possible to the scraper A B and not havethe said scraper interfere with the operation of the wheel L placed uponthe journals of said axle. The Wheels L are made with wide rims so asnot to sink into the ground leveled or smoothed by the scraper. To theaxle J, near its journals, are attached two short stakes, M, to keep theplatform upon which the driver stands in place and prevent it fromcoming in contact with the wheels L. The platform consists of a widecentral board, N, and two narrow boards, O, placed at its side edges. Tothe upper and lower sides of the forward part of the wide board N aresecurely bolted two narrow strips, P, between the projecting ends ofwhich the narrow side strips O work, and which serve as guides to saidside strips O. To the rear part of the central board N is pivoted thecenter of a cross-bar, Q, the ends of which are pivoted to the rearparts of the side strips O. rIhe forward ends of the side strips O arepivoted to the rear side ofthe plank A by means of eyebolts, eye-plates,staples, or other convenient means. By this construction the platform NO can adjust itself as the inclination of the scraper A B is adjusted,allowing the wheels to freely follow the line of draft. l is a knife orshear, designed for use more especially in cleaning private roads fromgrass, &c. The cutter B is set at an inclination, as shown in Fig. 2,and to its ends are attached or upon them are formed two arms, S, whichproject vertically to pass up along the forward side of the scraper A B.The upper ends of the arms S are bent to the rearward at right angles topass through holes in the upper part of the plank A, Where they aresecured in place by nuts. The arms S should be of such a length as toleave a clear space between the blade It and the lower edge of thescraper-plate B for the dirt to pass through, so that it may fall backinto the place from which it was raised, leaving the surface of theroadway as level and smooth as it was before, so that all that will benecessary will beto rake oli' the grass, Snc., cut oi beneath thesurface by the cutter R. To the plank A are attached the lower ends oftWo bars or stakes, T, which may have handles U attached to thein at ornear their upper ends, and which are designed t'or the driver to takehold of 01 lean against when standing?l1 upon the upper edge of theplank A, or i'or him to fasten his reins to when desired. By thisconstruction the driver, by standing upon the plank A, can throw hisWhole right upon the scraper. Then less Weight is required upon thescraper he can Stand upon the forward part of' the platform N O, and bystanding;A upon the rear end ofthe platform N he can with his weightraise the scraper A B entirely away from the ground, enabling him topass along t'reely without at all operating upon the ground. Thisconstruction also enables the driver, by adjusting' his position uponthe platform N 0, to raise and hold the scraperplate away from and atany desired distance above the ground, so as to lill all cavities andleave the surface perfectly smooth and level; or he can deposit at anydesired point the whole or any part of the soil accumulated before thescraper for forming a ridge or illing a cavity.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. The self-adjusting platform N O, in combination withthe scraper A B, Wheels and axle L J, and adjustable connecting-bar I,substantially as herein shown and described, and for the purpose setforth.

2. The adiustable U-shaped connecting-bar I, in combination with thescraper A B and Wheels and axle L J, substantially as herein shown anddescribed, and for the purpose set forth.

3. The cutter R S, in combination with the scraper A B, substantially asherein shown and described, and for the purpose setforth.
